To find out how many more people live in China than in India, we need to compare the two populations.

China's population: \(1.45 \times 10^9\)

India's population: \(1,400,000,000\), which is the same as \(1.4 \times 10^9\).

Now, we can calculate the difference:

\[ 1.45 \times 10^9 - 1.4 \times 10^9 = (1.45 - 1.4) \times 10^9 = 0.05 \times 10^9 \]

Next, we convert \(0.05 \times 10^9\) to standard form:

\[ 0.05 \times 10^9 = 5 \times 10^{-2} \times 10^9 = 5 \times 10^7 \]

Thus, China has \(5 \times 10^7\) more people than India. The answer is:

5×10^7
